I TIE-PLATE.

Application filed December 2, 1910. Serial No. 595,218.

Be it known that I, CLIFTON W. SHER- MAN, a citizen of the UnitedStates, residing at Buffalo, in the county of Erie and State of NewYork, have invented new and useful rovements in Tie-Plates, of which theImp folr owing is a specification.

his invention relates to tie plates which are interposed between theundersides of railway rails and the upper sides of ties for the purposeof providing a better support for the rails and reducing the wear on thethe tie plate is provided.

v of 2 sheets: Figure 1 1s a top enables the rail to be the rail tocreep under ing load on the same.

.bling the tie,

ties.

One of the objects of this invention is to provide a tie plate of thischaracter which secured more firmly to the tie and thereby reduce thetendency of the action of a mov- Another object of this invention is toprovide means wh1ch permit of readily assemrail and tie plate andthereby facilitate proper installation of the railway.

My invention has the further object to provide a tie plate which will bereliably interlocked with the tie so as to effectually resist anytendency to move laterally relatively to the rail or to rotate about avertical axis which otherwise would operate to loosen the rail holdingmeans with which v In the accompanying drawings consisting plan View ofa rail, tie and tie plate showing'the manner in which these parts arearranged relatively to each other preparatory to interlocklng the tieplatewith the rail and securing the rail and tie plate to the tie. Flg.2 1s a similar view showing these parts secured together in theirrelative operative positions. Fig. 3 is a bottom plan view of the tieplate and the adjacent part of the rail.

A re resents a wooden tie and B a rail both of which .are of the usualand well are adapted to receive my improved tie plate.

0 represents the body of the tie plate which is generally of flat formand arranged horizontally between the upper side of the Specification ofLetters Patent. v Patented Sept. 24, 1912'. 1

tie and the underside of the base 6 of the e tie plate body rangedopposite one of the fastening hooks.

These spike openings are adapted to receive the shanks of spikes F, Fwhich are driven downwardly into the wooden tie so that the headsthereof engage over the base of the rail andfithereby securely connectthe tie, tie

plate and rail.

In assembling the parts the tie late is first placed in an obliqueposition etween the rail and tieso as to permit of passing the base ofthe rail downwardly between the bills of the fastening hooks D, D andengaging the undersides of the rail with the top of the tie plate body.The distance between the bills of the hooks is just sufiicient to permitthe base of the rail to be passed downwardly between the same, as shownin Fig. 1*. After the rail has been thus deposited upon the tie platethe latter is turned horizontally and about a vertical axis locatedmidway between the fastening hooks so as to carry the bills of the hooksover the adjacent parts of the base of the rail and to engage thebacksor shoulders of the hooks with the opposite edges of the rail base. Topermitof thus turning the body of the rail properly the underside of thesameis provided with a downwardly tapering or conical centering spur orpivot 9. After the tie,

rail and tie plate. have been preliminarily assembled preparatory tobeing fastened to-, as shown in- Fig. 1, the pivot or gether,

spur of the body is driven slightly into the upper surface of the tie bya slight downward blow u on the tie plate and rail,

whereby the tie plate is pivoted on the tie' plate has been thus driven.the tie plate is turned loo upper side of the rail base and the backsof the hooks engage this. base. B tie plate witx with opposite edges ofillllSPlVOllilllY connecting the the tie it is possible to turn the tieplate and engage the hooks thereof properly with the base of the railwith facility and without liability of getting these parts out of placerelatively to each other and also keeping the tie-iplate on the centralcient in supportin. the tie plateand the rail resting thereon. i Inaddition to thespikes F, the tie plate is fastened to the top of the tieby means of a locking spike F which passes through an opening 6 formedin a lateral enlargement h of the tie plate body which is arrangedadjacent to the outer side of the outer'hookD of the tie plate.

In assembling the parts the spike F on the inner side of the rail isfirst driven home partway leaving the same comparatively loose. Thespike F on the opposite or outer side of the rail is then driven fullyhome into the spike opening a so that its head engages with the adjacentpart of the rail base. The relativeconstruction of the rail, spike F andspike opening 6 is such that the outer side of this splke "engages onlywith the outer side of the spike opening 6 and the inner side of theshank of this spike engages only with the adjacent edge of the railbase, whereby the opposite edge of the rail base is firmly held orpressed against the back 0, the opposing'hook D of the tie plate. Thelocking spike'F is now driven fully home through the opening e of thetie plate and into the tie so that the head of this spike engages withthe top of the, tie plate and only the inner side of its shank engageswith the corresponding side of the spike opening whereby the back orshoulder of the adjacent fastening cent edge of the rail base. Thedriving of the first mentioned spike F is com leted before the drivingof the spike F 15 effected so that the head of the spike F bears againstthe base of the rail opposite to the hook D and the inner side of itsshank bears only against the adjacent edge of the rail base and theouter side of its shank bears only against the outer edge of the spikeopening -e, whereby this side of the rail baseis held down upon the tieplate, and the back of the hook I) is firmly held against the oppositeedge of the rail base. l/Vhile thus driving the several spikes the pivotspur g is forced fully into the tie so that the underside of the tieplate bears fully against the part'otthe tie where the latter is mostefiihook D is firmly crowded against the adjatbp of the tie. .Thedriving of the spikesalso causes the tie plate to turn slightly hori- -7ontall v on the vertical pivot spur, thereby increasing the grip of thebacks or shoulders of the tie plate hooks on the rail base andetl'ectuaiiy resisting the creeping action of the rail.

For the purpose of aiding in resisting lat- 6 eral displacement of thetie plate on the tie in all directions the underside of the body isprovided with one or more circular anchoring ribs 2' which are arrangedconcentrically relative to the pivot spur and arepreferably V-shaped incross section so that they may be easily driven into the top of the tie.Owing to the ircular form of the ribs 5 the same resist lateral strainsin all directions'and thereby reduce to a minimum the possibility ofdisplacing the late later-- ally. The underside of the tie p ate is alsoprovided with a plurality of radialanchoring ribs 3' which preferablyconnect with the circular ribs, 'as shown. These radial ribs are alsodriven into the tie and serve principally to resist turning of the tieplate about its vertical axis in a direction'whichtends. to'loosen theengagement of the hooks with the base of the, rail. For the purpose ofenabling the radial ribs to offer the greater resistance againstmovement of the hooks away from the rail base these ribs are maderatchet-shaped -in cross section, in other words the front side isbeveled or inclined and the rear sideis straight, abrupt or vertical, asshown inFigs. 5 and 6, which-faces are 50 arranged that the verticalfaces receive the thrust which tends. to move the hooks away fromthe-rail base and thereby most efi'ectually resist this tendency.

It will thus be noted that my improved construction of tie plate notonly provides. a substantial bearing for the rail on the tie and reducesthe wear on the latter but the same also permits of firmly holding therail both against lateral displacement when used on curves in theroadway'and also minimizes longitudinal creeping of the rail as the carsrun over the same. 1 I i I I claim as my invention: P 1.
